Description

TECHNICAL FIELD

[0001] The present invention relates to a liquid sample heating vaporizer for heating and vaporizing a liquid sample retained in a vaporization tank.BACKGROUND ART

[0002] A conventional liquid sample heating vaporizer is, as illustrated in FIG. 6, provided with a vaporization tank having an inlet port for introducing a liquid sample and an outlet port for leading out a vaporized liquid sample, and heaters for heating and vaporizing the liquid sample retained in the vaporization tank. The heaters are provided outside a bottom wall and side walls, and configured to heat the liquid sample through the bottom and side walls. Temperature control of the liquid sample at the time of heating is performed by using temperature detection values from a liquid temperature sensor that detects a temperature of the liquid sample, and a heater temperature sensor provided for the heaters.

[0003] However, in the above configuration, surfaces that heat the liquid sample are an inside surface o...
